Something like '/^\w+,\w+,\w*$/' maybe? (untested) http://php.net/reference.pcre.pattern.syntax

Thats got me a lot further - thanks I reduced it slightly to '/^\w+,\w+,' because at the end there is the possibility of an alpha-numeric character(s) OR nothing at all with the exception of a possible line break (note possible) It's the 'possibly nothing at all' which I am slightly stuck on

That's what the \w* means. That means "0 or more word-characters", as opposed to \w+ which means "1 or more word-characters. The $ after that means "end of string" which makes sure that it's the last thing in the string. In other words, \w* means some word-characters, or nothing at all. You'd need to handle the newline in much the same way. The URL I gave you should help out a lot with that. -- Jasper Bryant-Greene Freelance web developer http://jasper.bryant-greene.name/ If you find my advice useful, please consider donating to a poor student!
